Squeezing of a nonlocal photon fluid

Quantum fluids of light are an emerging tool employed in quantum many-body physics. Their amazing properties and versatility allow using them in a wide variety of fields including gravitation, quantum information, and simulation. However the implications of the quantum nature of light in nonlinear optical propagation are still missing many features. We theoretically predict classical spontaneous squeezing of a photon fluid in a nonlocal nonlinear medium. By using the so called Gamow vectors, we show that the quadratures of a coherent state get squeezed and that a maximal squeezing power exists. Our analysis holds true for temporal and spatial optical propagation in a highly nonlocal regime. These results lead to advances in the quantum photon fluids research and may inspire applications in fields like metrology and analogs of quantum gravity.

OUTNANO project starts!

OUTNANO is a Marie Curie Fellowship in the H2020 program funding activity on Out of Equilibrium Nano-photonics

The Marie Curie Fellow is Andrea Marini, a top level young scientist with an extended research career in Nonlinear Photonics.

A new approach for studying novel optical materials in out-of-equilibrium ultrafast dynamics is the goal of this interdisciplinary projects committing together ideas of statical mechanics of complex systems and nonlinear photonics. We will conceive a new generation of nonlinear devices operating at the fastest achievable speeds for classical and quantum applications.

Complexity in Nonlinear Photonics in Como

School description:

The school brings together experts in emerging photonic technologies and fundamental physics to share with young researchers their knowledge and interdisciplinary approaches for understanding and designing complex photonic systems. The areas covered by the school include: complexity of optical communication systems, in particular topics such as the nonlinear Fourier transform and transmission over multimode fibres, complexity in quantum systems emulated in photonics (including optical computing), PT-symmetric systems, complexity of emerging novel materials and components like meta-surfaces and micro-resonators. Importantly, the complexity in bio-medical photonic applications will be also considered as a high priority topic.
